ATTACHMENT FOR TALKING-MACHINES.-

Specification of Letters Patent. Patented Aug. 15,- 1911.

Application filed'February 2, 1909. Serial No. 475,686.

To all whom it may concern.-

Be'it known that I, EDWARD T. Connor, Jr., a citizen of the United States, and a resident of Morristown, in the county of Morris and State of New Jersey, have in vented certain new and useful Improvements in Attachments for Talking-Machines, of which the following is a specification.

My invention relates to attachments for talking machines, and particularly to talka ing machines employing a rotating record disk.

It has for its object to automatically stop the rotation of the disk as well as to disengage the needle from said disk when the end of the record has been reached; also, to provide extremely simple means to accomplish this result and which may readily beattached to apparatus already inruse, (no change in the same being required.

I am aware that various attachments have been devised to automatically stop the rotation of the disk, but-so far as I am aware,

needle itself, or do not disengage the needle from the record or other surface. The diaphragm, which is a very delicate and a most important part of the apparatus, is thus exposed to serious damage, and all movements of the needle will be reproduced to the annoyance ofthe listeners. -With my attachment, however, the needle is at once disengaged from the record disk as soon as the end of the piece is reached, and the motion of'the said'record disk arrested- The attachment, also, suited for any existing machine of the disk record type without requiring the slightest change in same, and is readily removed if not required.

The nature of my invention will be best understood in connection with the accompanying drawings in w'hich Figure l is a plan view showing my device attached. Fig. 2 is a side elevation. 'Fig. 3 is a detail viewshowing the attachment of the locking plate. Figs. 4 and 5 are side and front elevations respectively, illustrating the locking plate in locked position and the needle disengaged V Similar charactersof reference designate corresponding parts through the several views. Referring now to the drawings, 10 indicates a rotatable record disk mounted to rotate with a'support 11.. Over this disk 10 andresting upon apart of the unmarked portion of said disk is placed a plate 12 preferably provided with a circumferential groove 13 so that the same may be readily lifted off the disk 10 when removing the record.

This plate is of sufiicient surface to'allow it to be carried along with the disk 10 in its rotation. If there be not sufiicient friction to accomplish this, the underside may be covered with felt or the like. A hole 14 is bored horizontally through this plate 12 as near he center as possible, and through the same passes an arm 15 slidably held therein, so as to be adjustablefor various sizes of record disks, and is thus firmly supported .by the said plate. A handle 16 is provided to adjust the arm 15. At one.

end, the said arm is provided with a recessed stopconsisting of a flexible guidel? and block 17 forming with each other a suitable angle or broadly a recess so as to engage with a co-acting member on the re producer, in this case the edge 18 of a. locking plate 19. This edge is suitably beveled so that as contact is made between the stop and the plate 19, the latter is slightly raised, contact being first made at the bottom of the plate. An indicator gage 20 is carried by the head of the arm 15 to enablethe recessed stop to be properly set with respect to the record. The relation between D the parts is such that when the arm 15 is adjusted to' bring the gage to the particular line of the record at -.which it is desired thatv the playing should stop, then the recessed stop on said arm will also be in correct position to receive the member 19 on the reproducer, as soon as the rotation of the record has brought the needle to the line thereon at which the gage has been located as aforesaid. I

The plate 19 is secured to the reproducer 21, being held against itsrubber insulator 22; and its lower edge is arranged to be a slight distance above the point of the needle 23 so as not to make contact with the record disk 10 or indicator 20. As the edge 18 of plate 19 slides into the stop, the plate. 19 is slightly raisedas explained, raising the reproducer (which it will be understood piv-.

ots about the section of tubing 26 as an axis) and lifting thereby the needle 23 free of the record'disk 10 and also stopping the rotation of said disk. By making the arm 15 adjustable as explained, the stop may be set to cooperate with the plate 19 so that the needle 23 is disengaged from the disk 10 at practically the conclusion of the piece k and the movement of the disk arrested.

I claim 1. In a disk-record talking machine: a

bored through the same; an armvpassing slidably through said hole and supported by said plate; a stop at one end of said arm; and a locking member carried by the reproducer of said talking machine, adapted to lock in said stop when the needle has reached the end of the record and to disen age the needle from the said record disk. In a disk-record talking machine: a plate adapted to fit over and be carried by the record disk and having a horizontal hole bored through the same; an arm passing slidably through said hole and supported by said plate; a stop at one end of said arm; and a plate secured to the reproducer of said talking machine and having its lower edge a slight distance above the point of the needle, and being adapted to lock in said stop when the needle has reached the end of the record and to disengage the needle from the said record disk.

3.vIn-a disk-record talking machine: a plate of-largekbearing surface adapted to fit over and be carried by the record disk, and having a horizontal hole bored through the same; an arm passing slidably through said hole and supported by said plate; a stop at one end of said arm; and a thin plate secured to the reproducer of said talking machine, having its lower edge a slight dis tance above thevpoint'of the needle, and being adapted to lock in said stop when the needle has reached the end of the record,

the angle of contact between an edge of said plate and the stop being such as to lift the reproducer slightly and thereby disengage the needle from the said record disk.

4-. In combination With a disk-record talk- I ing machine having a pivotally supported reproducer,a member carried by the center portion of the record-disk'having a radially extensible arm provided at its outer end With a stop consisting of a' pair of vertically disposed members separated by a slight cleft, at least one of said members being flexible; and a vertically disposed plate carried by the reproducer, to enter edgewise and lock in the cleft of the stop to tilt the reproducer and its needle ofi the record and stop the r0- tation of the-record.

5. In combination with a disk-record talking machine having a pivotally supported reproducer,a member carried by the center portion of the record-disk having a radially extensible arm provided at its outer end with a stop consisting of a pair of vertically disposed members separated by a slight cleft, I

atleast one of said members being flexible; a vertically disposed plate carried by the reproducer, to enter edgewise and lock in the cleft of the stop to tilt the reproducer and its needle off the record and stop the rotation of the record; and an indicator gage on said outer end of the extensible-arm.
